Peach tree named 'GP45-11'
Kind Code:

A new and distinct variety of peach tree is characterized by producing a freestone fruit with good red coloration, and that is ripe for commercial harvesting and shipment between July 13-20 in the San Joaquin Valley of Central California. The new variety is closely similar to the ‘O'Henry’ peach tree (nonpatented) from which it is a bud sport and from which it is distinguishable in that the fruit matures earlier than the ‘O'Henry’ peach fruit, is more highly colored, has very good flavor and stores very well.

What is claimed is:

1. A new and distinct variety of peach tree having characteristics described and illustrated herein.



The peach cultivar of this invention is botanically identified as Prunus persica.


The variety denomination is ‘GP45-11’.


During the continued efforts to improve the quality of available fruit for the consumer, the inventor discovered a bud sport of the O'Henry/Peach variety (nonpatented) on a block of peaches in August of 1999. After reexamining the fruit in 2000, budwood was collected and budded on to Nemaguard rootstock in the dormant season of 2000/2001 on current site. Enough trees (11,403) of this invention were asexually reproduced to plant 59-66 acres. The resulting fruit produced in this planting produced highly colored fruit, with very good size, two weeks before the ‘O'Henry’ variety. In addition this fruit is very juicy with good flavor. The fruit produced in all respects is identical to the original bud sport.


The present invention (variety) was discovered in an ‘O'Henry’ peach planting in August of 1999 on the west side of Madera Avenue, approximately 3½ miles south of the town of Kerman, Calif. in the San Joaquin Valley of Central California. The new variety was asexually reproduced in the dormant season of 2000/2001 by bud grafting on Nemaguard rootstock. Enough trees were asexually reproduced to plant 59-66 acres of the new variety. The inventor carefully compared the asexually reproduced trees with the parent sport, including the fruit, and found they were identical in all respects.


The ‘GP45-11’ peach is characterized by producing a large freestone fruit that has good blush coloration and is ripe for commercial harvesting and shipping around July 13-20 in a normal year in the San Joaquin Valley of Central California. This new variety is a large fruit with a red blush and yellow flesh with red flecks. It is most similar to the ‘O'Henry’ peach tree (nonpatented) from which it is a bud sport. However, it is distinguishable in that it ripens approximately two weeks before the ‘O'Henry’ variety. The fruit of this new variety is large, with good flavor and good red color, which makes it quite acceptable to the consumer.


FIG. 1 illustrates, clockwise from top left: the front and back of whole leaves, whole leaves on a twig from a twig end, top, bottom and side views of the fruit displaying the characteristic skin color and shape, fruit cut in half displaying the flesh, pit cavity and pit in place, and pit.
